WEIGHT-MOTOR.

Specification of Letters Patent.

Patented. March 24, 1908.

Application filed July 13, 1907. Serial No. 383,678.

To all whom it may concern:

Be it known that I, JOHN CALVIN RACK- LEY, a citizen of the United States, residing at Robert Lee, in the county of Coke and State of Texas, have invented a new and usefiil right-Motor, of which the following is a specification.

This invention relates to a motor for driving a fan for cooling rooms, halls and other apartments. The object being to provide a simple, cheap and durable mechanism for revolving a fan by means of a cord and weight.

1 Another object of the invention refers to the winding mechanism wherein a drum on which the cord is wound and the first gear wheel are independently rotatable in one direction on the winding shaft, the latter having keyed thereon two ratchet wheels which engage respectively, pawls on the drum and on the gear wheel.

A further ob ect of the invention relates to a brake and stopping mechanism applied to a convex disk fast on the fan shaft.

Referring to the accompanyin drawings :Figure 1 is a side elevation of the motor shown as operating a fan. Fig. 2 is a'sectional view of the winding drum on the line 22 of Fig. 1. Fig. 3 is a sectional view on the line 3-3 of Fig. 2.

Similar numerals of reference indicate corres onding parts on all of the figures.

he motor is carried in a frame made in .any desired way, but as shown in the drawing, the bottom plate 1 and the perpendicular side plates 2 and 3 are integral and extend upwardly to the same height, the side plate 2 having an inwardly turned flange 4 to which one end of the top plate 5 is bolted, screwed or otherwise fastened. The opposite end of the top late 5 is turned down and similarly fastened to the inner face of the side late 3. The top plate 5 projects beyond t e side plate 2 and is bent upwardly at 6 to form. an offsetor lug 7 by means of which it is screwed to a fixed base, in this case a ceiling; A separate piece 8 of similar shape is fastened to the other end of the to plate and to the ceiling to support that en of the motor frame.

An upwardoflset 9 is made in the to plate 5 near the bent portion 6 which is per orated for a vertical driving shaft 10 the lower end of which shaft passes through a bearing 0 ening in the bottom plate 1 and projects a s ort distance beyond the frame where it is squared for. a winding crank or key (not shown).

' the shaft 10 turns to the right.

- Loosely mounted on the driving shaft 10 is a winding drum 11 having a flange 12 on its lower end, beneath which is a ratchet wheel 13 keyed to the shaft 10. The ratchet wheel 13 is held a short distance above the bottom plate by a bracket14 fixed to said plate and iaving a perforation through which the driving shaft passes. A pawl 15 is pivoted to the flange 12 of the drum to engage the ratchet wheel 13 when the shaft is turned to the left for revolving the drum to wind the cord 16 thereon and raise the weight 17.

Loosely mounted on the shaft 10 at the opposite end of the drum 11, but disconnected therefrom, is the master gear wheel 18, held close to the end of the drum by a ratchet wheel 19 keyed to the shaft 10, to serve as a flange for retaining the -cord on the drum. A pawl 20 is pivoted on the master gear wheel 18 and engages the ratchet wheel 19 to cause the rotation of said master wheel when When a key is applied to the shaft 10 and the latter turned to the left, the ratchet wheels 13 and 19 also turn, the one 13 engages the pawl 15 and revolves the drum, winding the cord 16 thereon and raises the weight 17. The other ratchet 19 slips past the pawl 20 and the master wheel remains at rest. After the weight has been wound to its full height, and the key released the cord is drawn by the weight from the drum, rotating it to the right and carrying the pawl 15 with it. This pawl continues its engagement with the ratchet wheel 13, turning the shaft 10 and the ratchet wheel 19 to the right also. Moving in this direction the ratchet wheel 19 engages the pawl 20 and in turn carries themaster wheel 18 with it. v

The shaft 21, mounted in the frame and from which power is taken, is parallel to the driving shaft and in this instance carries afan 22 on an extension 23 reaching a suitable distance below the frame, the upper end of which shaft has fixed thereto below the top plate 5 a small pinion 24.

Between the driving shaft 10 and the shaft 21 are a plurality of parallel vertical shafts journaled in the base plate 1 and the top plate 5. Each shaft carries alternately at its up or and lower end a small pinion 25 and a arge gear wheel 26. These gears and pinions intermesh with one another, the gear wheel 18 on the drivin shaft and the pimons 24 on the fan shaft'in t o well known manner to give the fan shaft a rapid rotation. Below the pinion 24 on the shaft 21 is fixeda circular plate 27 with a convex under surface 28. Threaded in the left side frame 3 just below the disk is a' thumb screw 29 by means of which the speed of the motor may be changed or stopped altogether as will e described later. Fixed to the shaft 21 above the bot tomframe plate 1 is a collar'30 to which on opposite sides are fastened two flat springs 31 which extend upwardly at a slight curve to the disk 27 and are attached to a hub 32 on its under side. Midway 'the'length of each flat spring 31 is fastened a weight 33 which cause the springs to bow ou'twardby centrifugal force when the shaft 21 rotates and pull the disk 27 downwardly, the latter being loose on the shaft. 1

When the regulator 34' which comprises the disk, fiat springs, weights thereon and collar, is in'the position indicated in Fig. 1 and'the-thumb screw 29 bears against its under surface near the hub, the friction between the'screw and the disk is sufiicient to revent the shaft -21 rotating. If the screw e backed out. a short distance it will bereleasedfrom'contaclz with thedisk and the motor will runif wound up, but the speed of rotation will depend on the distance the screw has been retracted, for as soon as the disk strikes the end of the screw as it is drawn downwardly by the centrifugal action of'the regulator, the speed will be held constant at on the shaft, a ratchet wheel keyed to one end of the shaft and a pawl pivoted to sa1d ('lIUlIllD. engagement with the ratchet 4 wheel, a second ratchet wheel keyed to the shaft near the opposite end and a pawl pivoted to said gear wheel'in engagement with said second ratchet wheel,.-and a weighted pord attached to 'said drum adapted when 5.

wound thereon to operate the mechanism.

2. A motor comprising a train of gearing, having a power driving shaft and a power delivery shaftat opposite ends of said train, a'windin'g drum having a flange on one end and loosely mounted on said driving shaft, a gear wheel loosely mounted on the same shaft in close proximity to and serving as aflange for the other end of the drum but having independent movement, ratchet wheels on opposite-ends of said driving shaft a pawl on the drum and one on the gear wheel'in engagement with the respective ratchet wheels, and a cord and weight attached to said drum.

3. A motor comprising a train of gearing,

having a drivin shaft, a drum and a gear Wheel each loose y mounted thereon, a cord and Weight attached to said drum, separate ratchet devices for connecting the shaft to said drum and to said gear wheel, and so disposed that when t'he shaft is turned in one direction the drum will be turned by one ratchet and-wind the cord on the drum without operating the gear wheeland when the weight turns the drum in opposite direction it will turn the shaft and the latter through the other ratchet, rotate the gear wheel and the motor.

In testimony thatl claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

JOHN CALVIN RACKLEY.
